Applying geoscience to Australia's most important challenges

Abstract

The principal objective of the H4 Project was to evaluate existing techniques and develop new enabling technologies in geochronology
and isotope geoscience to significantly improve our ability to constrain the timing of ore formation and, therefore, expand
predictive capabilities.
A fundamental goal was the evaluation of existing dating methods and interpretations, particularly with respect to gold deposits
in low grade terrains, and to investigate potential new dating methods such as 40Ar/39Ar laser probe analyses of mica-bearing
pyrite linked to gold mineralisation. A second major goal of the H4 project was to initiate development of halogen/noble gas
geochemistry technology and expertise within the pmd *CRC to enable this unique geochemical method to be applied to ore deposits
in the flagship terrains in the second stage programme of pmd *CRC.
